Irbene is a ghost town (legally - village) in Ance Parish, Ventspils Municipality in northwestern Latvia. In 1971, the Soviet Union established a secret radar center "Звезда" ("Star" in Russian; later acquired by Ventspils International Radio Astronomy Centre in 1990s and still in operation) and built a settlement for military officers and their families, naming it Irbene because of nearby river Irbe.

The town had a school, shop, sport and concert halls. However, the town was not marked on maps. Only the holders of a special permit were able to access Irbene.

After the withdrawal of the Soviet Army in 1993 the town became abandoned.
